4. Operating Instructions
Using the Stamina InLine Back Stretch Bench for spinal decompression is a straightforward process:
- Sit Down: Sit on the padded bench with your back facing the arm supports.
- Secure Ankles: Place your ankles into the padded ankle supports. Ensure they are comfortably and securely positioned. The easy-to-use ankle lock will help secure your ankles.
- Lie Back: Gently lie back onto the padded bench, positioning your upper body so that your arms can rest over the arm supports.
- Initiate Decompression: Reach for the traction lever located on the side of the bench. Slowly and gently crank the lever to begin stretching your spine. You should feel a gentle pull and decompression in your back. Do not over-stretch or cause pain.
- Hold and Release: Hold the stretched position for a comfortable duration, typically 30 seconds to a minute, as recommended by your healthcare professional. To release, slowly reverse the cranking motion of the lever. It is recommended to release the arm supports first, then the ankle supports, allowing your body to relax gradually.
- Repeat: You may repeat the stretching process as desired, ensuring adequate rest between repetitions.
